DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS

Disclosed are a display substrate and a manufacturing method therefor, and a display apparatus. The display substrate comprises a base and a plurality of sub-pixels arranged in an array on the base, wherein each sub-pixel comprises: a data line pattern extending in a first direction, a power signal line pattern comprising a portion extending in the first direction, and a sub-pixel driving circuit, the sub-pixel driving circuit comprising: two switch transistors, a driving transistor and a storage capacitor, wherein a first polar plate of the storage capacitor is coupled to a gate electrode of the driving transistor, and a second polar plate of the storage capacitor is coupled to the power signal line pattern; and second poles of the two switch transistors are both coupled to a first pole of the driving transistor, and an orthographic projection, on the base, of the second pole of at least one of the two switch transistors at least partially overlaps with an orthographic projection, on the base, of the power s
